Description

本発明は、車両のフロントカウル部にワイパ装置が固定配置された車両の前部構造に関する。   The present invention relates to a vehicle front structure in which a wiper device is fixedly disposed on a front cowl portion of a vehicle.

自動車等の車両のカウルボックス部位の上方には、ウインドシールドガラスを払拭するワイパ装置が配置されている。ここで、このワイパ装置に上方から保護対象物が衝突すると、その衝撃荷重がワイパ装置に作用するが、このような場合であっても、衝突エネルギー（衝突荷重）を吸収できる構造が望まれている。   A wiper device for wiping the windshield glass is disposed above a cowl box portion of a vehicle such as an automobile. Here, when an object to be protected collides with the wiper device from above, the impact load acts on the wiper device. Even in such a case, a structure capable of absorbing the collision energy (collision load) is desired. Yes.

そこで、車両のカウルボックス部位の上方に配置されたワイパ装置を、上方から衝撃荷重が作用した際には車両下方へ退避させることによって、当該衝突エネルギーを消費し、衝突荷重を吸収緩和するように構成されているものがある（特許文献１、あるいは特許文献２参照）。   Therefore, the wiper device disposed above the cowl box portion of the vehicle is retracted downward when the impact load is applied from above, thereby consuming the collision energy and absorbing and mitigating the collision load. Some are configured (see Patent Document 1 or Patent Document 2).

ところが、前記各特許文献に示されたような構成を採用するためには、カウルボックス部位におけるワイパ装置とカウルボックスの底壁との間に、ワイパ装置が車両下方に退避するためのスペースが充分に確保されている必要がある。   However, in order to employ the configuration shown in each of the above-mentioned patent documents, there is sufficient space for the wiper device to retreat below the vehicle between the wiper device at the cowl box portion and the bottom wall of the cowl box. It is necessary to be secured.

しかしながら、このようなスペースの確保は、保護対象物が衝突するという万一のためのものであり、通常時においては全く無駄なスペースとなり、カウルボックス構成部品の大型化及びコスト高をもたらすこととなっている。一方、これとは逆に、前記スペースを確保しておかなければ、ワイパ装置が車両下方に退避することができず、衝突荷重が充分に吸収緩和されないといった問題を有している。
特開２００１−７１８７１号公報 特開２００２−２００９６９号公報 However, securing such a space is for the sake of a collision of the object to be protected, and it is a wasteful space in normal times, leading to an increase in the size and cost of the cowl box components. It has become. On the other hand, if the space is not secured, there is a problem that the wiper device cannot be retracted below the vehicle, and the collision load is not sufficiently absorbed and relaxed.
JP 2001-71871 A Japanese Patent Laid-Open No. 2002-200969

本発明は上記事実を考慮し、大型のカウルボックスを必要とせず、コンパクトで安価な構成により、衝突荷重がワイパ装置に作用したときにはワイパ装置を車両下方に充分に退避させることができる車両の前部構造を得ることが目的である。   In consideration of the above facts, the present invention does not require a large cowl box, and has a compact and inexpensive configuration, so that when the collision load acts on the wiper device, the wiper device can be sufficiently retracted below the vehicle. The purpose is to obtain a partial structure.

請求項１に係る発明の車両の前部構造は、車両のフロントカウル部にワイパ装置が固定配置された車両の前部構造において、前記フロントカウル部は、前記ワイパ装置の下端部から所定距離離間して位置する底壁部と、前記ワイパ装置の少なくとも一部が通過可能に前記底壁部に形成された開口部と、前記開口部を閉塞すると共に前記ワイパ装置の下方への退避移動によって破壊または変形することで前記開口部を前記ワイパ装置通過可能状態とする閉塞部材と、を有する、ことを特徴としている。   According to a first aspect of the present invention, there is provided a vehicle front structure in which a wiper device is fixedly disposed on a front cowl portion of the vehicle, wherein the front cowl portion is spaced a predetermined distance from a lower end portion of the wiper device. A bottom wall portion positioned at the same time, an opening formed in the bottom wall portion so that at least a part of the wiper device can pass through, and the opening portion is closed and destroyed by a retreating movement of the wiper device downward. Alternatively, it includes a closing member that deforms the opening to allow the wiper device to pass therethrough.

請求項１記載の車両の前部構造では、フロントカウル部に設けられた底壁部には、ワイパ装置の少なくとも一部が通過可能な開口部が形成されており、さらに、当該開口部は閉塞部材によって閉塞されている。しかも、この閉塞部材は、ワイパ装置の下方への退避移動によって破壊または変形することにより、開口部を前記ワイパ装置、特にピボット部位やワイパモータ部位などの下方への突出構造物のある部位を少なくとも通過可能状態とすることができる。   In the front structure of the vehicle according to claim 1, an opening through which at least a part of the wiper device can pass is formed in the bottom wall provided in the front cowl, and the opening is closed. It is blocked by the member. In addition, the blocking member breaks or deforms due to the retreating movement of the wiper device downward, so that the opening passes at least through the wiper device, particularly at a part having a downward projecting structure such as a pivot part or a wiper motor part. It can be made possible.

したがって、ワイパ装置の上方から衝撃荷重が作用した際には、ワイパ装置の下方への退避移動によって閉塞部材が破壊または変形して、開口部が前記ワイパ装置通過可能状態となり、ワイパ装置の少なくとも一部が開口部を通過して退避移動し、当該衝突エネルギーが消費されて衝突荷重が吸収緩和される。   Therefore, when an impact load is applied from above the wiper device, the closing member is broken or deformed by the retreating movement of the wiper device downward, so that the opening portion is allowed to pass through the wiper device, and at least one of the wiper devices. The part retreats through the opening, the collision energy is consumed, and the collision load is absorbed and relaxed.

このように、フロントカウル部のスペース（底壁部とワイパ装置との間のスペース）を通常時（保護対象物の非衝突時）における必要最小限として確保し、しかも、保護対象物の衝突時には、ワイパ装置の下方への退避移動に伴って閉塞部材を破壊または変形させることで開口部を前記ワイパ装置通過可能状態として、ワイパ装置の退避移動ストロークを充分に確保することができる。   In this way, the space in the front cowl (space between the bottom wall and the wiper device) is secured as a necessary minimum during normal operation (when the object to be protected does not collide), and when the object to be protected collides. The opening member can be passed through the wiper device by destroying or deforming the closing member as the wiper device is retracted downward, so that the retracting stroke of the wiper device can be sufficiently secured.

請求項２に係る発明の車両の前部構造は、請求項１記載の車両の前部構造において、前記閉塞部材は、少なくとも前記開口部周縁への取付け部分が弾性材料から成り、所定の負荷で前記変形して前記開口部から離脱するプレート部材である、ことを特徴としている。   A vehicle front structure according to a second aspect of the present invention is the vehicle front structure according to the first aspect, wherein at least a portion of the closing member attached to the periphery of the opening is made of an elastic material, and a predetermined load is applied. It is a plate member that is deformed and detached from the opening.

請求項２記載の車両の前部構造では、閉塞部材は、少なくとも開口部周縁への取付け部分が弾性材料から成るプレート部材であるため、ワイパ装置が下方へ退避移動する際には、破壊されることなく変形して開口部から容易に外れ、ワイパ装置の開口部を介した退避移動の妨げにならない。またしかも、このように閉塞部材は破壊されることなく変形して開口部から外れるため、当該閉塞部材を繰り返し使用することができる。   In the vehicle front structure according to claim 2, since the closing member is a plate member made of an elastic material at least at the periphery of the opening, it is destroyed when the wiper device retreats downward. Without being deformed, it easily disengages from the opening and does not hinder the retreat movement through the opening of the wiper device. In addition, since the blocking member is deformed without being broken and is removed from the opening, the blocking member can be used repeatedly.

なお、前述の如くプレート部材の前記開口部周縁への取付け部分を弾性材料によって形成するに限らず、当該プレート部材を全体として弾性材料によって形成する構成としてもよい。この場合であっても、所定の負荷で変形して開口部から離脱させることができる。   As described above, the portion of the plate member attached to the periphery of the opening is not limited to being formed of an elastic material, and the plate member may be formed of an elastic material as a whole. Even in this case, it can be deformed with a predetermined load and detached from the opening.

請求項３に係る発明の車両の前部構造は、請求項１または請求項２記載の車両の前部構造において、前記閉塞部材は、前記フロントカウル部の内部から排水する排水ダクトを有する、ことを特徴としている。   A vehicle front structure according to a third aspect of the present invention is the vehicle front structure according to the first or second aspect, wherein the closing member has a drainage duct for draining from the inside of the front cowl portion. It is characterized by.

請求項３記載の車両の前部構造では、万一、フロントカウル部内に雨水や洗車水が浸入したとしても、閉塞部材の排水ダクトによって、フロントカウル部の内部から水を外部に排水することができる。このため、ワイパモータなどの浸水が防止される。   In the vehicle front structure according to claim 3, even if rain water or car wash water intrudes into the front cowl portion, the drainage duct of the closing member can drain water from the front cowl portion to the outside. it can. For this reason, infiltration of a wiper motor or the like is prevented.

図１には本発明の第１の実施の形態に係る車両の前部構造１０の構成が断面図にて示されている。   FIG. 1 is a sectional view showing the structure of a vehicle front structure 10 according to a first embodiment of the present invention.

この前部構造１０においては、フロントカウル部１２にワイパ装置３０が固定配置されている。   In the front structure 10, the wiper device 30 is fixedly disposed on the front cowl portion 12.

フロントカウル部１２は、上方が開口する断面コ字形（ボックス断面）に形成されており、このフロントカウル部１２の後部上面に車両のフロントガラス１４の下端部が接合され、また、フロントカウル部１２の前部上面は車両のエンジンフード１６の後端縁に達している。また、フロントカウル部１２の上部開口、すなわち、フロントガラス１４の下端縁とフロントカウル部１２の前部上面との間には、カウルガーニッシュ１８が取り付けられている。   The front cowl portion 12 is formed in a U-shaped cross section (box cross section) that opens upward, and the lower end portion of the vehicle windshield 14 is joined to the upper surface of the rear portion of the front cowl portion 12. The front upper surface of the vehicle reaches the rear edge of the engine hood 16 of the vehicle. Further, a cowl garnish 18 is attached between the upper opening of the front cowl part 12, that is, between the lower end edge of the windshield 14 and the front upper surface of the front cowl part 12.

フロントカウル部１２内には、ワイパ装置３０が固定配置されている。ワイパ装置３０は、ピボットホルダ３２に回動可能にピボット軸３４が支持されており、さらにピボット軸３４にはピボットレバー３６及びワイパアーム３８が取り付けられた構成となっており、図示を省略したワイパモータの駆動力をリンク機構によって伝達してワイパアーム３８が往復回動する。   A wiper device 30 is fixedly disposed in the front cowl portion 12. The wiper device 30 is configured such that a pivot shaft 34 is rotatably supported by a pivot holder 32, and a pivot lever 36 and a wiper arm 38 are attached to the pivot shaft 34. The driving force is transmitted by the link mechanism, and the wiper arm 38 reciprocates.

ここで、このワイパ装置３０の最下端部、すなわち、ピボットホルダ３２の下端部とフロントカウル部１２の底壁部２０との間には、通常時（保護対象物の非衝突時）における必要最小限の隙間Ｓが確保されている。   Here, the lowest necessary part in the normal state (when the object to be protected does not collide) is provided between the lowermost end part of the wiper device 30, that is, between the lower end part of the pivot holder 32 and the bottom wall part 20 of the front cowl part 12. A limited gap S is secured.

またさらに、フロントカウル部１２の底壁部２０には、開口部２２が形成されており、さらに、この開口部２２には閉塞部材としてのプレート２４が取り付けられている。開口部２２は、ワイパ装置３０の少なくとも一部、特に、ワイパ装置３０のピボットホルダ３２や図示しないワイパモータなどのように下方へ突出する構造物のある部位に対応して、それら突出構造物が通過可能な大きさに形成されている。また、プレート２４は、弾性材料（樹脂材あるいはゴム材等）によって形成されており、所定の負荷で変形して開口部２２から離脱することができる。   Furthermore, an opening 22 is formed in the bottom wall portion 20 of the front cowl portion 12, and a plate 24 as a closing member is attached to the opening 22. The opening 22 corresponds to at least a part of the wiper device 30, particularly a portion where there is a structure projecting downward, such as a pivot holder 32 of the wiper device 30 or a wiper motor (not shown). It is formed in a possible size. The plate 24 is made of an elastic material (such as a resin material or a rubber material), and can be detached from the opening 22 by being deformed with a predetermined load.

これにより、通常は開口部２２はプレート２４によって閉塞されており、ワイパ装置３０の下方への退避移動によって例えばピボットホルダ３２の下部等がプレート２４に接触し、当該プレート２４が変形することで開口部２２から離脱して、開口部２２を前記ワイパ装置３０の通過可能状態とすることができる構成である。   As a result, the opening 22 is normally closed by the plate 24, and the lower part of the pivot holder 32, for example, comes into contact with the plate 24 by the retreating movement of the wiper device 30, and the plate 24 is deformed to open the opening. In this configuration, the wiper device 30 can pass through the opening 22 by being detached from the portion 22.

なお、前述の如くプレート２４を全体として弾性材料によって形成するに限らず、少なくとも開口部２２周縁への取付け部分を弾性材料によって形成し、所定の負荷で変形して開口部２２から離脱するように構成することもできる。   As described above, the plate 24 is not limited to be formed of an elastic material as a whole, but at least a portion attached to the periphery of the opening 22 is formed of an elastic material, and is deformed with a predetermined load so as to be detached from the opening 22. It can also be configured.

次に本第１の実施の形態の作用を説明する。   Next, the operation of the first embodiment will be described.

上記構成の車両の前部構造１０では、フロントカウル部１２に設けられた底壁部２０には、ワイパ装置３０の少なくとも一部が通過可能な開口部２２が形成されており、さらに、当該開口部２２はプレート２４によって閉塞されている。しかも、このプレート２４は、ワイパ装置３０の下方への退避移動によって開口部２２から離脱することができる。   In the vehicle front structure 10 having the above-described configuration, an opening 22 through which at least a part of the wiper device 30 can pass is formed in the bottom wall portion 20 provided in the front cowl portion 12. The part 22 is closed by a plate 24. Moreover, the plate 24 can be detached from the opening 22 by the retreating movement of the wiper device 30 downward.

したがって、ワイパ装置３０の上方から衝撃荷重が作用した際には、図２に示す如く、ワイパ装置３０（図２において、ピボットホルダ３２）の下方への退避移動によって当該プレート２４が変形することで開口部２２から離脱して、開口部２２が前記ワイパ装置３０の通過可能状態となり、ワイパ装置３０の少なくとも一部（ピボットホルダ３２の下部等）が開口部２２を通過して退避移動し、当該衝突エネルギーが消費されて衝突荷重が吸収緩和される。   Therefore, when an impact load is applied from above the wiper device 30, the plate 24 is deformed by the retreating movement of the wiper device 30 (pivot holder 32 in FIG. 2) downward as shown in FIG. After detaching from the opening 22, the opening 22 is allowed to pass through the wiper device 30, and at least a part of the wiper device 30 (such as a lower portion of the pivot holder 32) retreats through the opening 22, The collision energy is consumed and the collision load is absorbed and relaxed.

このように、フロントカウル部１２のスペース（底壁部２０とワイパ装置３０のピボットホルダ３２最下端部との間のスペース）を通常時（保護対象物の非衝突時）における必要最小限（隙間Ｓ）として確保し、しかも、保護対象物の衝突時には、ワイパ装置３０の下方への退避移動に伴ってプレート２４を変形させることで開口部２２を前記ワイパ装置３０通過可能状態として、ワイパ装置３０の退避移動ストロークを充分に確保することができる。   As described above, the space of the front cowl portion 12 (the space between the bottom wall portion 20 and the lowermost end portion of the pivot holder 32 of the wiper device 30) is the minimum necessary (gap between the objects to be protected is not colliding). S), and when the object to be protected collides, the plate 24 is deformed as the wiper device 30 is retracted downward, so that the opening 22 can be passed through the wiper device 30 so that the wiper device 30 can pass. It is possible to sufficiently secure the retreat movement stroke.

またさらに、この前部構造１０においては、閉塞部材としてのプレート２４が弾性材料によって形成されており、所定の負荷で変形して開口部２２から離脱する構成であるため、プレート２４は破壊されることなく変形して開口部２２から容易に外れるため、当該プレート２４を繰り返し使用することもできる。   Still further, in the front structure 10, the plate 24 as a closing member is formed of an elastic material, and is configured to be deformed by a predetermined load and detached from the opening 22, so that the plate 24 is destroyed. The plate 24 can be repeatedly used because it is deformed without being easily removed from the opening 22.

次に、本発明の他の実施の形態を説明する。   Next, another embodiment of the present invention will be described.

なお、前記第１の実施の形態と基本的に同一の部品には前記第１の実施の形態と同一の符号を付与しその説明を省略する。   Note that components that are basically the same as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted.

図３には、第２の実施の形態に係る車両の前部構造４０の構成が断面図にて示されている。   FIG. 3 is a sectional view showing the configuration of the vehicle front structure 40 according to the second embodiment.

この車両の前部構造４０は、前述した第１の実施の形態に係る車両の前部構造１０と基本的に同じ構成であるが、フロントカウル部１２の底壁部２０に形成された開口部２２には、閉塞部材としてのプレート４２が取り付けられている。プレート４２は、開口部２２の周縁に接着されて取り付けられており、所定の負荷で破壊して開口部２２から離脱あるいは当該開口部２２を開放することができる。   The vehicle front structure 40 has basically the same configuration as the vehicle front structure 10 according to the first embodiment described above, but has an opening formed in the bottom wall portion 20 of the front cowl portion 12. A plate 42 as a closing member is attached to 22. The plate 42 is attached by being adhered to the periphery of the opening 22, and can be detached from the opening 22 or opened by opening with a predetermined load.

これにより、この車両の前部構造４０においても、通常は開口部２２はプレート４２によって閉塞されており、ワイパ装置３０の下方への退避移動によって当該プレート４２が破壊することで開口部２２から離脱して開口部２２を開放し、開口部２２を前記ワイパ装置３０の通過可能状態とすることができる構成である。   As a result, also in the front structure 40 of this vehicle, the opening 22 is normally closed by the plate 42, and the plate 42 is broken by the retreating movement of the wiper device 30 downward, so that it is detached from the opening 22. Thus, the opening 22 is opened, and the opening 22 can pass through the wiper device 30.

上記構成の車両の前部構造４０では、ワイパ装置３０の上方から衝撃荷重が作用した際には、ワイパ装置３０の下方への退避移動によってプレート４２が破壊することで開口部２２から離脱し、開口部２２が前記ワイパ装置３０の通過可能状態となり、ワイパ装置３０の少なくとも一部（ピボットホルダ３２の下部等）が開口部２２を通過して退避移動し、当該衝突エネルギーが消費されて衝突荷重が吸収緩和される。   In the front structure 40 of the vehicle configured as described above, when an impact load is applied from above the wiper device 30, the plate 42 is broken by the retreating movement of the wiper device 30 below, so that the plate 42 breaks away from the opening 22. The opening portion 22 is allowed to pass through the wiper device 30, and at least a part of the wiper device 30 (such as a lower part of the pivot holder 32) retreats through the opening portion 22, and the collision energy is consumed and the collision load Is absorbed and relaxed.

このように、フロントカウル部１２のスペース（底壁部２０とワイパ装置３０のピボットホルダ３２最下端部との間のスペース）を通常時（保護対象物の非衝突時）における必要最小限として確保し、しかも、保護対象物の衝突時には、ワイパ装置３０の下方への退避移動に伴ってプレート４２を破壊することで開口部２２を前記ワイパ装置３０通過可能状態として、ワイパ装置３０の退避移動ストロークを充分に確保することができる。   Thus, the space of the front cowl portion 12 (the space between the bottom wall portion 20 and the lowermost end portion of the pivot holder 32 of the wiper device 30) is ensured as a necessary minimum during normal times (when the object to be protected does not collide). Moreover, when the object to be protected collides, the retracting movement stroke of the wiper device 30 is made such that the opening portion 22 is allowed to pass through the wiper device 30 by breaking the plate 42 as the wiper device 30 is retreated downward. Can be secured sufficiently.

なお、前述の如くプレート４２を開口部２２の周縁に接着して取り付けるに際し、他の同様の手段を用いて（例えば、部材を溶着して）取り付けるように構成してもよい。さらに、前記プレート４２が破壊することで開口部２２から離脱して開口部２２を開放し易くするために、当該プレート４２の一部に切り込みを設けたり、部分的に薄肉に形成する構成としてもよい。   In addition, when attaching the plate 42 by adhering to the periphery of the opening part 22 as mentioned above, you may comprise so that it may attach using another similar means (for example, welding a member). Furthermore, in order to make it easy to open the opening 22 by detaching from the opening 22 due to the destruction of the plate 42, it is also possible to provide a notch in a part of the plate 42 or to make it partially thin. Good.

次に、図４には、第３の実施の形態に係る車両の前部構造５０の構成が断面図にて示されている。   Next, FIG. 4 shows a cross-sectional view of the configuration of the vehicle front structure 50 according to the third embodiment.

この車両の前部構造５０は、前述した第１の実施の形態に係る車両の前部構造１０と基本的に同じ構成であるが、フロントカウル部１２の底壁部２０に形成された開口部２２には、閉塞部材５２が取り付けられている。閉塞部材５２は、前述した第１の実施の形態に係るプレート２４と同様に、弾性材料によって形成されており、所定の負荷で変形して開口部２２から離脱することができる。またさらに、この閉塞部材５２には、排水ダクト５４が設けられている。これにより、閉塞部材５２は、フロントカウル部１２の内部から排水することができる構成である。   The vehicle front structure 50 has basically the same configuration as the vehicle front structure 10 according to the first embodiment described above, but an opening formed in the bottom wall portion 20 of the front cowl portion 12. A closing member 52 is attached to 22. The closing member 52 is formed of an elastic material, like the plate 24 according to the first embodiment described above, and can be deformed with a predetermined load and detached from the opening 22. Furthermore, the closing member 52 is provided with a drain duct 54. Accordingly, the closing member 52 is configured to be able to drain from the inside of the front cowl portion 12.

上記構成の車両の前部構造５０においては、前記第１の実施の形態に係る車両の前部構造１０と同様の効果を奏すると共に、閉塞部材５２の排水ダクト５４によって、フロントカウル部１２の内部から水を外部に排水することができる。このため、ワイパ装置３０駆動用のワイパモータや電気的接続コネクタ部分などの浸水を好適に防止することができる。   In the vehicle front structure 50 having the above-described configuration, the same effect as that of the vehicle front structure 10 according to the first embodiment can be obtained, and the interior of the front cowl portion 12 can be obtained by the drainage duct 54 of the closing member 52. Water can be drained to the outside. For this reason, it is possible to suitably prevent water from entering the wiper motor for driving the wiper device 30 and the electrical connection connector portion.
